Products.TemporaryFolder 6.1

Zope temporary folder support.

Overview

Zope temporary storage / folder support.

Please note

Temporary Folders and the temporarystorage ZODB storage depend on the tempstorage package, which is known to randomly lose data under Zope 4 and up. If you want to use the sessioning support in Zope please visit https://zope.readthedocs.io/en/latest/zopebook/Sessions.html#alternative-server-side-session-backends-for-zope-4 for alternate sessioning implementations that don’t use Temporary Folder.

Because it is unsafe, Zope will no longer magically create a Temporary Folder object at /temp_folder. If you think you still need a Temporary Folder, please add a temporary storage database definition like the one below to your Zope configuration, restart Zope, and use the ZMI add list to create an object of type ZODB Mount Point. If the storage configuration is valid you will see a list of configured mount points and the option to create the container in the ZODB:

<zodb_db temporary>
    <temporarystorage>
      name Temporary database (for sessions)
    </temporarystorage>
    mount-point /temp_folder
    container-class Products.TemporaryFolder.TemporaryContainer
</zodb_db>

When upgrading from version 5.3 to 6.0 and removing the ZODB Mount Point configuration shown above from your Zope configuration you need to manually delete the /temp_folder object in the ZMI before restarting your Zope instance with version 6.0. If you see tracebacks ZConfig.ConfigurationError: No database configured for mount point at /temp_folder after the upgrade, please reinstate the zodb_db temporary Zope configuration as shown above, restart Zope and manually delete /temp_folder. Then remove the zodb_db temporary configuration and restart Zope.
